CVE-2017-15650 (opens in a new tab)How to fix?
Upgrade Debian:13 musl to version 1.1.17-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream musl package and not the musl package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
musl libc before 1.1.17 has a buffer overflow via crafted DNS replies because dns_parse_callback in network/lookup_name.c does not restrict the number of addresses, and thus an attacker can provide an unexpected number by sending A records in a reply to an AAAA query.
